What's the ratio between the volume of the cylinder and the volume of the cone? (assume both have radius r and height h)
Choose the correct answer in each of the following :
A right circular cylinder and a right circular cone have the same radius and the same volume. The ratio of the height of the cylinder to that of the cone is
(a) 3:5 (b) 2:5 (c) 3:1 (d) 1:3
Among a cylinder (of radius r and height h=r), a cone (of radius r and height h=r) and a sphere of radius r the __ will have the maximum volume.
